The Maricopa County Sheriff's Office served search warrants at three west Valley locations this morning, and county sources tell New Times the boys in beige are investigating some of their own for alleged ties to human- and drug-smuggling operations.

The Sheriff's Office has not said what deputies are investigating and did not immediately respond to New Times' request for comment.
